| 摘 要： | 简要介绍了一般剪切带的成分变异、体积变化、流体流动的研究进展、着重讨论了榴辉岩相剪切带流体流动与变形变质作用的关系，认为剪切带应变不均匀性、变质作用不均一性和流体存在状态及流体超压是榴辉岩形成和保存的3个主要制约因素。

| Abstract: | This paper reviews the progress of shear zones on the basis of composition variation,volume change and fluid flow,and discusses the relationship between fluid flow and deformation/metamorphism in the eclogite facies shear zones.It is suggested that the three constraint factors for the eclogites forming and preserving are as follows: the heterogeneity of the shear strain and metamorphism,and the state and ultra pressure of the fluid in the shear zones during subduction and uplift,respectively. |

| Keywords: | shear zone composition variation volume change fluid flow deformation and metamorphism |
